MOTILITY TRADEOFFS IN SYMBIOSES: A COLLECTION OF INTERESTING HYPOTHESES

Symbiosis is an integral part of life, with most organisms on Earth engaged in symbiotic interactions ranging from mutualistic to parasitic. Classic studies into symbioses looked at simple pairwise interactions, like clownfish and sea anemones or pearlfish and sea cucumbers. However, focusing on these pairwise interactions ignores the ways in which complex communities of hosts and symbionts affect each other. Symbiosis research has not yet taken full advantage of metacommunity theory, which describes interactions between spatially disparate communities of organisms affecting each other through dispersal. Traditionally, this framework has been used to study communities along connected environmental patches. However, if we consider a host to be a patch, we can use this framework to study how host controls, symbiont interactions, and dispersal affect the structure and diversity of symbiont communities. One distinction between a host patch and an environmental patch is that the host patch is potentially mobile. We propose that, due to coevolutionary tradeoffs, host-symbiont systems tend towards an inverse relationship between host mobility and symbiont mobility, depending on environment, transmission mode, host and symbiont taxa, and whether or not the association is obligate for one or both species.
